thanks goes to windsurf and snow for bring down some demo gear to gerroa for the weekend.
Ended up trying and using in in my heats the 83 tri fin with a 5-8 Alpha. (got third in the first round), pretty stoked considering it was the first time on the board and had moved up to the pro's (opens) from am's.
Was little bit unsure of how this board would go down the line and thought it would be a fsw wave with a couple of extra fins.
After the first wave being awkward due to not have the footstraps open enough had a heap of fun on this board, it really works like a thruster surfboard ( i have both thruster and a quad surf board) you can get drive by pumping the board done the wave just as you would a surf board and the board turns very nicely and easly.
The board doesnt seem like a big 83, that could just be my winter weight.
I am comparing to my Quattro twin fin which i am still in love with but would be something i would definitely consider if was in the market for a new board. worth a demo !
Next to try will be quad.
The alpha felt well balanced, although bigger than i normally use and more of a powerful sail ( i use equivalent of zones) the combo worked ok due to the wind being marginal. I should have tried the 5.1 fly (next time)
Thanks Windsurf and snow
By the way i am 78 kgs + steamer and we were sailing in 6-17 knots with waste to the odd shoulder high waves.
I saw on the JP website that the 2011 trifin is the 2010 wave just with 2 extra fins... same shape, so its pretty much guaranteed to be heaps better than a FSW.
